KATO LockOne®

A Superior Locking Force

KATO’s LockOne is a revolutionary positive locking product designed to prevent a standard nut from loosening free under vibration. Upon tightening, the LockOne coils stretch, providing superior locking force. Unlike nuts with nylon or locking compounds, the KATO LockOne does not degrade with each use. Due to the unique LockOne design, the assembly is FOD free. Save on assembly cost! No expensive replacement nuts! The LockOne lightweight design is perfect for use on weight sensitive applications. KATO LockOne replaces double nut (jam nuts), cotter pins & safety-wire.

LockOne can be easily substituted into existing designs. LockOne is reusable, does not degrade with each cycle. Made from 304 Stainless Steel WPB, LockOne is naturally corrosion resistant.

Design and Assembly

Designing in LockOne couldn’t be easier! Simply account for an extra three threads to the bolt length. That’s it! It’s compact nature allows for ease of use in designs with weight restrictions and maintenance schedules.

KATO’s LockOne is fast and easy to install. No locking compounds to apply. A standard dodecagonal (12-Point) socket installs the LockOne at the same time as the nut, minimizing installation time. LockOne may also be installed on exisiting applications, simply thread LockOne on the preinstalled nut. LockOne is adjustable and removable after installation with the same 12-point socket.

LockOne Performance

Superior Force

Once positioned in front of nut, LockOne engages the bolt along pitch diameter inducing spring forces axially and radially. These forces hold LockOne in place, preventing bolts and nuts from loosening free under vibration.

Installation is Easy!

Simply load the LockOne into the 12-Point socket.

Load the standard nut on top of the LockOne.

Tighten as normal.

If there is a gap between the LockOne and the nut, simply hand tighten the LockOne until it is flush with the nut..
